Lab Report 1
Analysis:
Part 1 Observations:
-
With “cloth to plastic” the electrons of the negatively charged plastic go into the
electroscope causing the leaves to repel.
-
With the “glass to tissue” the electrons from the electroscope are attracted to positively
charged glass rod causing the leaves to repel.

-
In step number 4 the negatively charged plastic and the positively charged glass rod cause
a state of equilibrium making the leaves to remain in place because the charges are being
cancelled out.
-
In step 5 when the electrons from the plastic go into the electroscope your finger will act
as a ground meaning the electrons will go into your finger and the leaves will return to
their state of equilibrium.
Part 2 observations:
-
In step 6 both plastic rods repelled because they were both negatively charged.
-
In step 7 both glass rods repelled because they were both positively charged.
-
In step 8 the negatively charged plastic rod was attracted to positively charged glass rod.
-
In step 9 the metal rod was attracted to the plastic rod.
-
In step 10 one could see that the attraction of the metal rod was stronger and this is
because the metal is a conductor meaning that it has a free-flow of electrons within its
nuclear structure so it can because polarized pushing all of its electrons to one extreme
and causing a net positive charge on one side and a net negative on another
Part 3 observations:
-
The gray separator was negatively charged, and the white separator was positively
charged.
-
The net charged should be something very close to zero.
